PREVENTING DUST FROM ENTERING RAILROAD-CARS.

Specification of Letters Patent No.

To all whom it may concern:

Be it known that I, DANIEL S. DARLING, of Brooklyn, in the county ofKings and State of New York, have invented a new and useful improvementin the manner of applying or arranging reversible deflectors forconcentrating the dust arising under railroad-cars from or by the motionof the wheels and for expelling it at the end of the train; and I dohereby declare that the following is afull, clear, and exact descriptionof the same, reference being had to the accompanying drawings, formingpart of this specification, in which Figure 1, is a side elevation of acar and. locomotive, having my improved deflectors attached to them.Fig. 2, is an inverted plan of the locomotive and car, with deflectors.

Similar letters of reference in each of the several figures indicatecorresponding parts.

The nature of my invention consists in arranging a series of deflectorsalong the sides of the locomotive, and entire train of cars, in such amanner that a series of funnel shaped chambers will be formed, which runinto each other, and form a continuous channel for the dust and airunderthe car to be confined in while the funnel shaped mouths at thefront of the locomotive receive a powerful outside pressure of air,which, by the position of the deflectors is forced into less than itsordinary space, and causes an extraordinary suction current under thetrain, which concentrates andcarries the dust arising from the wheelswith it into the artificial channel under the cars, and confines ituntil it escapes at the end of the train. The open mouths of thedeflectors on the sides of the cars, also serv ing as channels for anyside dust which may come in contact with them to be sucked through intothe central channel.

My invention consists, 2d, in so arranging the deflectors, that they canbe reversed, and be made to effect the same object while the cars aremoving from, as they do when they are returning to, their stations.

To enable others skilled in the art, to make and use my invention, Iwill proceed to describe its construction and operation.

A, in the accompanying drawings, represents a rail car, and B, thelocomotive, both of which may be made in the ordinary manner.

C, C, and D, D, are the deflectors which 10,402, dated January 10, 1854.

are placed upon the locomotive and cars. The mouths of those, C, C,are'made to stand out even with the sides of the cars, so as to presentan extra resistance at the commencement, to the atmosphere, and give theset screws when it is desirable to get at the'under portion of theengine, they being made stationary and independent of those,

D, D, on the cars, because they do not require to be reversedthe enginebeing" turned around instead. The position and funnel shape of thedeflectors will be clearly seen in the drawing; and by examining Fig. 2,the manner in which they are presented to the dust and air under thelocomotive and train of cars, and form the main channel, will be clearlyseen. Thus it will be seen that the entering of dust into the cars, isin a great measure prevented. The deflectors, D, D, are susceptible ofbeing reversed as, the cars change their course, they being loosely hungon rods, cl, d, at their center, as shown in the drawing; said rodsbeing secured in a standard, 0, attached to, and extending down from,the

bottom of the cars, and havinghorizontal ends, or steps, 6, e, for thelower ends of the rods, d, d, to rest inthe upper ends of said rodsbeing secured in crossbars, f, f, attached to the framing of the bottomof the cars.

F, F, are rods,'or flexible connections, by' I which all the deflectorsof each car, are

connected together these connections, as

will beevident'from the drawing, by their arrangement, allow of thedeflectors all be ing reversed at one time, from the position shown inthe drawing, when the train changes its'coursek G, H, are two chains,attached to the links, or flexible connections at each end of the cars,in the manner shown in the draw- -ing--it is by these chains that thedeflectors can be reversed, when desirable, for by sim-v ply drawingslightly upon the chain, ,G, which works in a friction pulley, thedeflectors will occupy the position shown in Fig. 2, and by pulling, ina similar manner, upon the chain, H, they will occupy a position thereverse of that shown.

It should be understood that these deflectors cover the sides of thetrucks entirely,

and close up the space between themthey extending from the bottom of thecar, down nearly even with the tracks, and along the entire length ofthe whole train of .cars. The car connections beingcovered by a canvasapron, g, which makes the channel formed by the deflectors, continuous,and keeps the dust confined until it escapes at the extreme end of thetrain. The cross bars, f, f, turn on'a journal to admit of thedeflectors being easily removed, by taking out the key at the lower endof rod, Z, d, and also'to'pern it of access to the truck wheels, I

What I claim to secure by Letters Patent, is

1. Arranging a series of deflectors along the sides of the locomotive,and entire train of cars, in such a manner that a series of tunnelshaped chambers will be formed, which run into each other, and form acontinuous channel for the dust and air under the car to be confined in,while the funnel as my invention, and desire shaped mouths at the frontof the locomoing as channels for any side dust which may come in contactwith them to be sucked through into the central channel, substantiallyas herein described.

2. I also claim the mannenherein described, and shown in the drawing, ofreversing the deflectors, so that they will effeet the desired object inwhatever direction the train is going, substantially as specified.
